UN and Multinational authorities for Environment Conservation

There are several multinational authorities and organizations that focus on environmental issues and work towards promoting sustainable development, protecting ecosystems, and addressing climate change. Here are some prominent examples:

1. United Nations Environment Programme (UNEP): UNEP is a specialized agency of the United Nations that coordinates international environmental activities and assists developing countries in implementing sound environmental policies. It provides guidance, conducts research, and facilitates cooperation among nations to tackle environmental challenges.

2. Intergovernmental Panel on Climate Change (IPCC): The IPCC is a scientific body established by the United Nations and the World Meteorological Organization (WMO). It provides policymakers with regular assessments of the scientific basis of climate change, its impacts, and potential response strategies.

3. World Health Organization (WHO): Although primarily focused on public health, the WHO plays a vital role in addressing environmental health issues. It monitors and assesses environmental risks, promotes policies for sustainable development, and advocates for measures to mitigate environmental hazards.

4. United Nations Framework Convention on Climate Change (UNFCCC): The UNFCCC is an international treaty established to combat climate change. It serves as a platform for nations to negotiate and implement agreements on reducing greenhouse gas emissions, adapting to climate change impacts, and providing financial and technical support to developing countries.

5. International Union for Conservation of Nature (IUCN): The IUCN is a global organization dedicated to nature conservation and sustainable development. It assesses the conservation status of species, promotes protected areas, and advises on environmental policies and practices.

6. World Wildlife Fund (WWF): The WWF is an international conservation organization that works to protect the world's most vulnerable ecosystems and species. It engages in field projects, conducts research, and advocates for policies that promote sustainable development and reduce environmental degradation.

7. Green Climate Fund (GCF): The GCF is a financial mechanism established under the UNFCCC to support developing countries in their efforts to mitigate and adapt to climate change. It provides financial assistance for projects that promote low-emission and climate-resilient development.

8. Convention on Biological Diversity (CBD): The CBD is an international treaty aimed at conserving biodiversity, promoting sustainable use of biological resources, and ensuring equitable sharing of benefits arising from genetic resources. It sets goals and targets for biodiversity conservation and facilitates cooperation among nations.

These multinational authorities and organizations play critical roles in addressing global environmental challenges, providing scientific expertise, promoting international cooperation, and facilitating the implementation of policies and actions to protect the environment and ensure a sustainable future.

geostationary and sun-synchronous

Orbital characteristics of Remote sensing satellite geostationary and sun-synchronous Orbits in Remote Sensing Orbit = the path a satellite follows around the Earth. The orbit determines what part of Earth the satellite can see , how often it revisits , and what applications it is good for . Remote sensing satellites mainly use two standard orbits : Geostationary Orbit (GEO) Sun-Synchronous Orbit (SSO) Geostationary Satellites (GEO) Characteristics Altitude : ~35,786 km above the equator. Period : 24 hours → same as Earth's rotation. Orbit type : Circular, directly above the equator . Appears "stationary" over one fixed point on Earth. Concepts & Terminologies Geosynchronous = orbit period matches Earth's rotation (24h). Geostationary = special type of geosynchronous orbit directly above equator → looks fixed. Continuous coverage : Can monitor the same area all the time. Applications Weather...

Disaster Management

1. Disaster Risk Analysis → Disaster Risk Reduction → Disaster Management Cycle Disaster Risk Analysis is the first step in managing disasters. It involves assessing potential hazards, identifying vulnerable populations, and estimating possible impacts. Once risks are identified, Disaster Risk Reduction (DRR) strategies come into play. DRR aims to reduce risk and enhance resilience through planning, infrastructure development, and policy enforcement. The Disaster Management Cycle then ensures a structured approach by dividing actions into pre-disaster, during-disaster, and post-disaster phases . Example Connection: Imagine a coastal city prone to cyclones: Risk Analysis identifies low-lying areas and weak infrastructure. Risk Reduction includes building seawalls, enforcing strict building codes, and training residents for emergency situations. The Disaster Management Cycle ensures ongoing preparedness, immediate response during a cyclone, and long-term recovery afterw...

Linear Arrays Along-Track Scanners or Pushbroom Scanners

Multispectral Imaging Using Linear Arrays (Along-Track Scanners or Pushbroom Scanners) Multispectral Imaging: As previously defined, this involves capturing images using multiple sensors that are sensitive to different wavelengths of electromagnetic radiation. Linear Array of Detectors (A): This refers to a row of discrete detectors arranged in a straight line. Each detector is responsible for measuring the radiation within a specific wavelength band. Focal Plane (B): This is the plane where the image is formed by the lens system. It is the location where the detectors are placed to capture the focused image. Formed by Lens Systems (C): The lens system is responsible for collecting and focusing the incoming radiation onto the focal plane. It acts like a camera lens, creating a sharp image of the scene. Ground Resolution Cell (D): As previously defined, this is the smallest area on the ground that can be resolved by a remote sensing sensor. In the case of linear array scanne...

Discrete Detectors and Scanning mirrors Across the track scanner Whisk broom scanner.

Multispectral Imaging Using Discrete Detectors and Scanning Mirrors (Across-Track Scanner or Whisk Broom Scanner) Multispectral Imaging: This technique involves capturing images of the Earth's surface using multiple sensors that are sensitive to different wavelengths of electromagnetic radiation. This allows for the identification of various features and materials based on their spectral signatures. Discrete Detectors: These are individual sensors that are arranged in a linear or array configuration. Each detector is responsible for measuring the radiation within a specific wavelength band. Scanning Mirrors: These are optical components that are used to deflect the incoming radiation onto the discrete detectors. By moving the mirrors, the sensor can scan across the scene, capturing data from different points. Across-Track Scanner or Whisk Broom Scanner: This refers to the scanning mechanism where the mirror moves perpendicular to the direction of flight. This allows for t...
